[AIRFLOW-4316] support setting kubernetes_environment_variables config section from env var (#5668)

When AIRFLOW_KUBERNETES_ENVIRONMENT_VARIABLES__AIRFLOW_HOME is set in
the scheduler, AIRFLOW_HOME should be set for workers, not airflow_home.

>          Issue Type: Bug
>          Components: configuration, contrib
>    Affects Versions: 1.10.3
>            Reporter: Vlad Precup
>            Assignee: QP Hou
>            Priority: Major
>              Labels: configuration, kubernetes

>   Original Estimate: 24h
>  Remaining Estimate: 24h

> All the environment variable names declared under the kubernetes_environment_variables section are converted to lowercase in the newly generated pods when running Airflow with the KubernetesExecutor in version 1.10.3.
> The behavior is not aligned with the comments in the documentation / code comments in the default config file, airflow.cfg.
> Investigation helper:
> Since we are treating all the sections uniformly in the configuration component, all the keys are lowered (i.e. `configuration.py`, line 342 ->`key = env_var.replace(section_prefix, '').lower()`)
> Please also write (a) unit test(s) for this special case.
